从另一个叫一个班。 PHP

Question

我有两节课。一个用于邀请，另一个用于通知，我将通知推送到设备。

我希望在数据库中插入邀请时调用通知类。

我已经使用通知类扩展了Invitation类，但它无效。我得到一个空输出。

如果我运行单个邀请或单个通知类，则两者都可以正常工作。

邀请班：

 <?php

require 'database.php';
require 'notification.php';

class Invitation extends notification
{
    private $sender_id,$date,$invitee_no,$status,$invitations,$user_name,$contact_id,$contact_name;
    private $notify;

    public function setNotification($message,$user_name) {
        $this->send($message, $user_name); // calling superclass method
    }

    function Invitation($sender_id,$date,$invitee_no,$status,$user_name,$contact_id,$contact_name)
    {

        $this->sender_id = $sender_id;
        $this->date= $date;
        $this->invitee_no = $invitee_no;
        $this->status = $status;
        $this->user_name = $user_name;
        $this->contact_id = $contact_id;
        $this->contact_name = $contact_name;
        // $this -> invitations = $invitations;

    }

    function sendInvite()
    {

        $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME);
        $dbConnection = $database->getDB();

        $stmt = $dbConnection->prepare("select * from Invitation where user_name =? and sender_id = ?");
        $stmt->execute(array($this->user_name,$this->sender_id));
        $rows = $stmt->rowCount();


        if ($rows > 0) {
            $response = array("status" => -3, "message" => "Invitation exists.", "user_name" => $this->user_name);
            return $response;
        }

        $this->date = "";
        $this->invitee_no = "";
        $this->status = "0";
        $this->contact_id = 0;
        $this->contact_name = "";

        echo $this->user_name;
        echo $this->sender_id;

        $stmt = $dbConnection->prepare("insert into Invitation(sender_id,date,invitee_no,status,user_name,contact_id,contact_name) values(?,?,?,?,?,?,?)");

        $stmt->execute(array($this->sender_id, $this->date, $this->invitee_no, $this->status, $this->user_name,$this->contact_id,$this->contact_name));

        $rows = $stmt->rowCount();
        $Id = $dbConnection->lastInsertId();


        $stmt = $dbConnection->prepare("select * from Invitation where invitation_id=?");
        $stmt->execute(array($Id));
        $invitation = $stmt->fetch(PDO::FETCH_ASSOC);

        if ($rows < 1) {

            $response = array("status" => -1, "message" => "Failed to send Invitation., unknown reason");
            return $response;

        } else {


          //  $notify = new notification();
          //  $resp = $notify->send($message, $this->user_name);

            $response = array("status" => 1, "message" => "Invitation sent.", "Invitation:" => $invitation);
            return $response;

        }

    }

通知：

    <?php

require 'database.php';

class notification
{

    private $text,$user_name;

    public function __construct()
    {
    }

    public function send($text,$userName)
    {

        $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME);
        $dbConnection = $database->getDB();

        $stmt = $dbConnection->prepare("Select device_id from Users where user_name =?");
        $stmt->execute(array($userName));

        $result = $stmt->fetch(PDO::FETCH_ASSOC);
        $token = $result["device_id"];

       // echo $token;
       // echo $text;
       // echo $userName;

        if(!empty($token)) {
            echo $token;
            $response = $this->sendPush($text, $token, "AIzaSyBGwwJaThyLm-PhvgcbdYurj-bYQQ7XmCc");
        }
    }

    public function sendPush($text, $tokens, $apiKey)
    {

        $notification = array(
            "title" => "You got an invitation.",
            "text" => $text,
            "icon" => "ic_chat_bubble_white_48dp",
            'vibrate' => 3,
            'sound' => "default"
        );

        $msg = array
        (
            'message' => $text,
            'title' => 'You got an invitation.',
            'tickerText' => 'New Message',
            'largeIcon' => 'large_icon',
            'smallIcon' => 'small_icon'
        );
        $fields = array
        (
            'to' => $tokens,
            'data' => $msg,
            'notification' => $notification
        );

        $headers = array
        (
            'Authorization: key=' . $apiKey,
            'Content-Type: application/json'
        );

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, 'https://android.googleapis.com/fcm/send');
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

        $result = curl_exec($ch);
        echo($result);
        return $result;
        curl_close($ch);
    }
}
?>

sendInvite脚本：

    <?php

error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
ini_set('display_errors', '1');

require 'Invitation.php';
require 'notification.php';


$jsonText = file_get_contents('php://input');

if(empty($jsonText))
{
    $response = array("status"=>-2,"message"=>"Empty request");
    die(json_encode($response));
}

$json = json_decode($jsonText);

$sender_id = $json-> sender_id;
$user_name = $json -> user_name;


echo $sender_id;
echo $user_name;

$invitation = new Invitation($sender_id,"","","",$user_name,"","");
$response = $invitation->sendInvite();

$message =  'Hi,add me to your unique contact list and you never need to update any changes anymore!';

$invitation->setNotification($message,$user_name);

echo(json_encode($response));
?>

如何整合这个？

编辑：

我将require更改为require_once

更新代码：

邀请：

  <?php

require_once 'database.php';

require_once 'notification.php';

class Invitation extends notification
{
    private $sender_id,$date,$invitee_no,$status,$invitations,$user_name,$contact_id,$contact_name;
    private $notify;

    public function setNotify($message,$user_name) {
        $this->send($message, $user_name); // calling superclass method
    }

    function Invitation($sender_id,$date,$invitee_no,$status,$user_name,$contact_id,$contact_name)
    {

        $this->sender_id = $sender_id;
        $this->date= $date;
        $this->invitee_no = $invitee_no;
        $this->status = $status;
        $this->user_name = $user_name;
        $this->contact_id = $contact_id;
        $this->contact_name = $contact_name;
        // $this -> invitations = $invitations;

    }

    function sendInvite()
    {

        $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME);
        $dbConnection = $database->getDB();

        $stmt = $dbConnection->prepare("select * from Invitation where user_name =? and sender_id = ?");
        $stmt->execute(array($this->user_name,$this->sender_id));
        $rows = $stmt->rowCount();


        if ($rows > 0) {
            $response = array("status" => -3, "message" => "Invitation exists.", "user_name" => $this->user_name);
            return $response;
        }

        $this->date = "";
        $this->invitee_no = "";
        $this->status = "0";
        $this->contact_id = 0;
        $this->contact_name = "";

        $stmt = $dbConnection->prepare("insert into Invitation(sender_id,date,invitee_no,status,user_name,contact_id,contact_name) values(?,?,?,?,?,?,?)");

        $stmt->execute(array($this->sender_id, $this->date, $this->invitee_no, $this->status, $this->user_name,$this->contact_id,$this->contact_name));

        $rows = $stmt->rowCount();
        $Id = $dbConnection->lastInsertId();

        $stmt = $dbConnection->prepare("select * from Invitation where invitation_id=?");
        $stmt->execute(array($Id));
        $invitation = $stmt->fetch(PDO::FETCH_ASSOC);

        if ($rows < 1) {

            $response = array("status" => -1, "message" => "Failed to send Invitation., unknown reason");
            return $response;

        } else {


          //  $notify = new notification();
          //  $resp = $notify->send($message, $this->user_name);

            $response = array("status" => 1, "message" => "Invitation sent.", "Invitation:" => $invitation);
            return $response;

        }
    }

通知：

require_once 'database.php';

    private $text,$user_name;

    public function __construct()
    {

    }
    public function setNotification($text, $username) {

        $this->user_name = $username;
    }
    public function send($text, $username)
    {

        $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME);
        $dbConnection = $database->getDB();

        $stmt = $dbConnection->prepare("Select device_id from Users where user_name =?");

        $headers = array

        curl_close($ch);
    }

?>

sendInvite：

    <?php

error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
ini_set('display_errors', '1');

require_once 'Invitation.php';

$jsonText = file_get_contents('php://input');

if(empty($jsonText))
{
    $response = array("status"=>-2,"message"=>"Empty request");
    die(json_encode($response));
}

$json = json_decode($jsonText);

$sender_id = $json-> sender_id;
$user_name = $json -> user_name;


echo $sender_id;
echo $user_name;

$invitation = new Invitation($sender_id,"","","",$user_name,"","");
$response = $invitation->sendInvite();

$message =  'Hi,add me to your unique contact list and you never need to update any changes anymore!';

$invitation->setNotification($message,$user_name);


echo(json_encode($response));
?>

现在得到这样的输出：

请帮忙......谢谢..

Answer 1

在通知文件中声明一个类变量，并在构造函数中调用数据库。所有其他地方使用$this->dbConnection代替$dbConnection。

class notification
{

    private $text,$user_name;
    public $dbConnection

    public function __construct()
    {
            $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME);
            $this->dbConnection = $database->getDB();
    }

    public function send($text,$userName)
    {
        $stmt = $this->dbConnection->prepare("Select device_id from Users where user_name =?");
        $stmt->execute(array($userName));

        $result = $stmt->fetch(PDO::FETCH_ASSOC);
        $token = $result["device_id"];

然后在邀请php上删除require 'database.php';行并使用$this->dbConnection访问数据库函数

 function sendInvite()
    {

        $stmt = $this->dbConnection->prepare("select * from Invitation where user_name =? and sender_id = ?");
        $stmt->execute(array($this->user_name,$this->sender_id));
        $rows = $stmt->rowCount();

在其他情况下，你不需要重新发送通知＆＃39;再次上课，只需像这样访问它。

 $resp = $this->send($message, $this->user_name);

希望这有帮助。

将您的需求更改为require_once以避免包含问题。
